Default WOT - IGN1 stays at 0 - 11-18-2021, 09:26 PM

Recently I've noticed that under WOT that the power feels "back and forth" through the rpm range. By recently, I mean after adding BMS HX, BMS Inlets, AMS Lowers, aFe drop-ins.

I noticed in the log that my ign1 stays at 0 during the pull. Attached is the csv. Map 3 93

With the JB4 off, everything runs and feels like it should, only slower lol.

Anyone see anything wrong? No CELs

Current Mods:
JB 4 w/ fuel wires and EWG wires
BMS Heat Exchanger
BMS Inlets
AMS Lower Down Pipes
aFe Drop-ins
AddW1 Catch Can

Strange, log on map0 and map1 to compare?

I'll log map0 and map1 and share the results this evening. Any particular way you want the pulls done to give you the best data in the logs?

I'm sure you noticed that both these logs look normal! Try Map 3 to see if the zero Ign1 anomaly comes back. Hopefully it was just a fluke.

Looks good here, hopefully just a fluke or maybe even an app bug on the logging.

I noticed they looked good as well when I logged them. Did some pulls last night and was having the issue again.

Doing the following:
Uninstalling/Installing app
Uninstalling/Installing JB4 from car (visual inspect of plugs/wire/connections)
Reflashing stable firmware
Logging map0-map3

I may even pull cylinder 1's plug and look at it. I don't think they've ever been changed. I'm the second owner at 47k miles.

Having major issues.. see the attached two logs.
Went to log a map3 and car just didn't want to do anything. See log titled ISSUE.

Turned off the car and tried again. Log attached.

Tried a map2 and the same issue happened again. I'm not sure if it's safe to try anymore pulls at this point.

Not sure what to do other than disable the JB4.

These to me look more normal, but fighting poor fuel. From the logs it looks like the car is trying to adjust timing but then pulling back because of knock. What fuel are you using - brand/octane.

Do you have any other brands you can try? Fuel quality can be very regional, so nothing against Shell generally, but you might have better results with another brand. You could also try mixing a few gallons of E85 in to ensure Octane is not your problem.

Not seeing what the issue is in your log. Some DSC and throttle closure on the first run.

In any event generally speaking if map3 is having problems drop down to map2, or map1.
